If you go to this link and click "next"
http://elections.nytimes.com/2012/electoral-map
there is a nice d3 visualization.  

Instead of states: think media conditions (we have ~100)
Instead of electoral votes for radius: think how many discrepancies were resolved
Instead of dragging to explore voting outcomes: think which changes to the model you want to accept.
Instead of tooltips with electoral votes: have option to select 1, 2, or 3 best modification to the model.

Add a button at the bottom for "commit" and get a nice, shiny new model to play with.
